Application filed METCh of 18956.-,

To all whom it may concern:

Be it known thatwe, JOHNARMS and CHES- TER E. ARMS, citizens of theUnited States, residing at South Lyon, county of Oakland, State ofMichigan, have invented a certain new and useful Improvement inDehorning- Clippers; and we declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

Ourinvention has for its object certain new and useful improvements indehorning-clippers; and itconsists of the construction, combination, andarrangement of devices hereinafter described and claimed, andillustrated in the accompanying drawings, in whichl Figure l is a viewin elevation. Fig. 2 is a view in section on the line 2 2, Fig. l. Fig.

3 is a view in section on the line 3 3, Fig. l.

Fig. 4 is a view in section on the line 4 4, Fig. l, when the levers arein closed position, as indicated in dotted lines in Fig. l. Fig. 5 is aview in perspective, showing features of our invention, certain partsbeing broken away.

Our invention aims to provide an article of this description of superiorefficiency and utility and which will not be liable to get out of order.

Ve carry out our invention as follows; A represents a suitable frame,preferably made of two similar parts A A2, spaced apart in any suitablemanner, as by intervening partitions or shoulders a ct', which may ormay not be integral with one of theportions of the' frame.

B and B indicate two cutter-blades having a reciprocatory engagement insaid frame. These blades are preferably formed with V- shaped cuttingedges of reverse form, so as to give a shear cut.

An important feature of our invention is in the provision of means toreciprocate both of the knives. This we accomplish by means of levers Cand C', fulcrumed to said frame at its lower corners, as indicated at cand c, each of said levers being eccentrically connected with saidknives B B', respectively,

ybevclosed on the horn.

by connecting-links, links D D and D D Serial No5 585,330. (No model.)

connecting said levers eccentrically with the knife B and links E E andE E connecting said levers eccentrically with the knife B.

The knife B' may be provided with a stiffening-bridge h, to theextremities of which the links D D and D D are pivotally connected, asshown at d d. The links connect the knife B and the knife B to thelevers O C on opposite sides of the fulcrum of the respective levers, asindicated more particularly in Figs. l and 3.

We do not limit ourselves to any particular manner of constructing theoperating-levers C C; but they are shown constructed each with ametallic head C2, having ears on opposite sides of the fulcrum, saidlinks being connected with said ears of said levers.

The knives B B', it will be seen, are located between the two portionsA' A2 of the frame, said frames forming guideways for thereciprocationof the knives. The knife B we prefer to form withprojecting arms b b, said arms bearing on the inner edges of thepartitions or Vshoulders a ct'. These arms are made to overlap theadjacent portions of the knife B, and the parts are so constructed thatthe knives cannot be opened far enough for the edges of the knife B andthe arms h to pass by each other and lock. An interference of the knivesthe one with the other in their reciprocation is thus prevented.

Ribs or Iianges co2 project inwardly from the side edges of theframe-section A2 near one end of such section and form bracing-guidesfor the sliding cutter B to prevent any tendency of such cutter tospring out of the plane of its movement, especially when the two4cutters are farthest apart and about to We prefer to form the port-ionsA A2 of the frame outwardly deflecting at their lower ends, as indicatedin Fig. 2, to give room for the ready operation of the links E E and EE. The levers C C are formed with stops c2 to limit the inward movementAof said levers.

The operation of the device will now be understood. By spreading thelevers apart the knives are opened to engage over the horn. Then byforcing the levers together the knives are closed upon the horn to clipit. In closing the levers together it will be observed that the links EE and E E exert an upward IOO movement of the knife B, while the links DD and D D cause a downward movement of the knife B'. l

It will be perceived that when the implement is open to engage a hornthe leverage upon the knives is the shortest at the very beginning ofthe desired cut. It is also evident that the larger the horn the shorterwill be the initial leverage, these features being of special advantagein the implement embodied in our invention and are features not to befound, it is believed, in any other implement s of this class.

What we claim as our invention is- A dehorner comprising duplicatesuperposed frames having intermediate filling- X pieces spacing themapart a proper distance, r the frames being outwardly and oppositelydeiiected atone end, and one of the frames being formed at its innerside edges near one end with ribs or tracks a2, oppositelydisposedcutters slidably mounted between the frames l and one of the cuttersbeing provided at its f opposite sides with projecting portions b'overlapping the other cutter 4and Working against the inner sides ofsaid filling-pieces, said other cutter beingadapted to ride on said ribswhen the implement is opened up for use, l

In testimony whereof we sign this specifcay tion in the presence of vtwowitnesses.
